Custom 5 Star Tune with HP Tuners NGauge

King of cars said:

I have the spd turbo adapters /roush cold air with the 5 star tune and noticed a huge difference in faster turbo spool between gears , way more responsive , less turbo lag and a good amount of power. This is on my daily street tune 91 octane and allowed abit more air for my kooks down pipe going on soon. Towing a 4500 lb boat was amazing the power difference made it feel noticeably easier. However I am having a issues with my cruise control now ever since doing the tune. If I set for 75 mph it will go to 74 and up to 78 then slow down and keeps changing all time jerky and has something to do with this big performance change I'm guessing. Gas ️ mileage definitely went down as it's holding higher RPM and wants to boost up way faster. Great value and will be doing dono pulls once kooks DP is installed.

I have mine set to 91 performance and during the 3.5 hour drive from phoenix to Havasu it did the exact same thing. Would not maintain the set cruise speed. I turned off adaptive cruise and using the standard cruise it still did the same thing. Set at 75 would go up to 77 and then pull back to 73 or 74. Then all of the sudden it slammed in to 7th gear unbelievably hard out of no where and for no reason. Definitely has me concerned. I just re-flashed to the 91 daily tune until I can figure out what the heck is going on.

Flashed this tune last week and so far have been largely unimpressed. Ebov opens during acceleration at low rpms causing the surge people complain about(their shop truck does this as well), LTFT's are off almost 30%, truck misfires at idle with plugs gapped correctly, tries to stall when putting it in reverse(i drove their shop truck and it does this as well), ACC causes downshifts with a hard thud and the throttle command ratio is far from ideal. I've seen 94% throttle plate at <20% accelerator input. I also appear to be getting significant tip in knock when in 4wd. These problems are with the offroad tune and probably why they don't recommend towing with it since its prone to tip in knock under load which is what im seeing in 4wd off road. I'll be emailing them tonight but i'm working on getting a new tuner lined up with significantly more experience. And I'll be using something other than an inertia dyno.

Old news though.


Mpt is the way to go.

I started with 5 Star.

It threw codes and the transmission logic was terrible.

MPT has been unbeatable for performance. Gearhead has the smoothest tranny. Whipple reminds me a lot of Gearhead. House of boost I haven’t bothered and IDS requires a bully dog last I checked and im not interested in changing platforms.
